On Verizon's website there used to be a tool to check to see if numbers were Verizon numbers. I can't seem to find that link anymore. Is it gone? Is there another way to check?
It isn't something where the numbers are manually entered. It's what's currently recorded in the Verizon Wireless customer system...so if their number exists in the Verizon system, it will show up on this system...
I think at first I tried it with my cellphone #, and it worked. Then for my post I changed it to the generic http://tirs.us/lookup/ or something like that. If I forget to remove my actual phone #, I didn't mean to ... my bad!
Try starting with "http://tirs.us/lookup/" (without the quote marks) in your address window, and then see if you can narrow it down to your actual cellphone number by selecting your state, area code, and number itself.
